| dc.description | We describe the history and results of our study of early-type disk galaxies with the Multi-Pupil Spectrograph of the 6m telescope (MPFS). With the new data we confirm the discovery of chemically distinct nuclei reported in 1992; now such nuclei are found in two dozens galaxies. The structure of chemically distinct features formed probably in secondary nuclear star-formation bursts seems to be complex and closely related to an appearance of separate circumnuclear disks. As by-product, we have also found inner polar gaseous disks in 4 non-interacting, regular spiral galaxies; this phenomenon may be related to bulge or bar triaxiality. Some preliminary statistical conclusions on stellar population properties in the nuclei and in the bulges of nearby S0 galaxies are given. | |
